Abstract:
An embodiment of an electric motor car control system includes a resistor connected parallel to a main motor cut-off switch, or a switch for grounding terminals of the main motor, to discharge electric charges accumulated in stray capacitances of the main motor, whereby the electric motor car control system can prevent electrical shocks due to electric charges accumulated in main motor stray capacitances.
